3. Improved study of the structure of e+e- → bb̄g events and limits on the anomalous chromomagnetic coupling of the b quark

Author

Abe, K, Abe, T, Adam, I, Akimoto, H, Aston, D, Baird, K, Baltay, C, Band, H, Barklow, T, Bauer, J, Bellodi, G, Berger, R, Blaylock, G, Bogart, JR, Bower, G, Brau, J, Breidenbach, M, Bugg, WM, Burke, D, Burnett, T, Burrows, P, Calcaterra, A, Cassell, R, and Chou, A

Abstract

The structure of 3-jet e+ e- → bb̄g events has been studied using hadronic Z0 decays recorded in the SLC Large Detector experiment at SLAC. Three-jet final states were selected and the charge-coupled-device-based vertex detector was used to identify two of the jets as b or b̄; the remaining jet in each event was tagged as the gluon jet. Distributions of the gluon energy and polar angle with respect to the electron beam were measured over the full kinematic range, and used to test the predictions of perturbative QCD. We find that beyond-leading-order QCD calculations are needed to reproduce the features seen in the data. The energy distribution is sensitive to an anomalous b chromomagnetic moment K at the bb̄g vertex. We measured κ to be consistent with zero and set 95% confidence level limits on its value, -0.06

Abstract

We present a measurement of the b-quark inclusive fragmentation function in Z0 decays using a novel kinematic B-hadron energy reconstruction technique. The measurement was performed using 350 000 hadronic Z0 events recorded in the SLD experiment at SLAC between 1997 and 1998. The small and stable SLC beam spot and the charge-coupled-device-based vertex detector were used to reconstruct B-decay vertices with high efficiency and purity, and to provide precise measurements of the kinematic quantities used in this technique. We measured the B energy with good efficiency and resolution over the full kinematic range. We compared the scaled B-hadron energy distribution with models of b-quark fragmentation and with several ad hoc functional forms. A number of models and functions are excluded by the data. The average scaled energy of weakly decaying B hadrons was measured to be (xb) = 0.709±0.003(stat)±0.003(syst)±0.002(model).

Abstract

A search for B 0s-B̄ 0s oscillations is performed using a sample of 400 000 hadronic Z 0 decays collected by the SLAG Large Detector experiment. The B 0s candidates are reconstructed in the B 0s→D -sX channel with D -s→Φπ -, K* 0K -. The B 0s production flavor is determined using the large forward-backward asymmetry of polarized Z 0→bb̄ decays and charge information in the hemisphere opposite that of the B 0s candidate. The decay flavor is tagged by the charge of the D ±s. From a sample of 361 candidates with an average B 0s purity of 40%, we exclude the following values of the oscillation frequency: Δm s

7. Direct measurements of ab and ac using vertex and kaon charge tags at the SLAC detector

Author

Abstract

Exploiting the manipulation of the SLAC Linear Collider electron-beam polarization, we present precise direct measurements of the parity-violation parameters Ac and Ab in the Z-boson-c-quark and Z-boson-b-quark coupling. Quark-antiquark discrimination is accomplished via a unique algorithm that takes advantage of the precise SLAC Large Detector charge coupled device vertex detector, employing the net charge of displaced vertices as well as the charge of kaons that emanate from those vertices. From the 1996-1998 sample of 400000 Z decays, produced with an average beam polarization of 73.4%, we find Ac = 0.673 ± 0.029(stat) ± 0.023(syst) and Ab = 0.919 ± 0.018(stat) ± 0.017(syst). © 2005 The American Physical Society.

Abstract

We report a search for Bs0-Bs0 oscillations using a sample of 400 000 hadronic Z0 decays collected by the SLD experiment. The analysis takes advantage of the electron beam polarization as well as information from the hemisphere opposite that of the reconstructed B decay to tag the B production flavor. The excellent resolution provided by the pixel CCD vertex detector is exploited to cleanly reconstruct both B and cascade D decay vertices, and tag the B decay flavor from the charge difference between them. We exclude the following values of the B s0-B̄s0 oscillation frequency: Δms

10. First symmetry tests in polarized Z0 decays to bbg

Author

Abstract

We have made the first direct symmetry tests in the decays of polarized Z0 bosons into fully identified bbg states, collected in the SLD experiment at SLAC. We searched for evidence of parity violation at the bbg vertex by studying the asymmetries in the b-quark polar- and azimuthal-angle distributions, and for evidence of T-odd, CP-even or CP-odd, final-state interactions by measuring angular correlations between the three-jet plane and the Z0 polarization. We found results consistent with standard model expectations and set 95% C. limits on anomalous contributions.

Abstract

We have developed a new technique for inclusive reconstruction of the energy of B hadrons. The excellent efficiency and resolution of this technique allow us to make the most precise determination of the b-quark fragmentation function, using e+e-→Z0 decays recorded in the SLAC Large Detector experiment. We compared our measurement with the predictions of a number of fragmentation models. We excluded several of these models and measured the average scaled energy of weakly decaying B hadrons to be (xB) = 0.714 ± 0.005(stat) ± 0.007(syst) ± 0.002 (model dependence). © 2000 The American Physical Society.

Abstract

We present the first direct measurement of As, the parity-violating coupling of the Z0 boson to the strange quark, using ∼550 000 e+e- → Z0 → hadrons events recorded by the SLC Large Detector with a polarized e- beam. We tagged Z0 → ss̄ events by the absence of B or D hadrons and the presence in each hemisphere of a high momentum K± or Ks0. Fitting the polar angle distributions of the strangeness-signed thrust axis gave As = 0.895 ± 0.066(stat) ± 0.062(syst). The analyzing power and uū + dd̄ background were constrained using the data, greatly reducing any model dependence. © 2000 The American Physical Society.

15. Production of π+, π-, K+, K -, p, and p̄ in light (uds), c, and b jets from Z0 decays

Abstract

We present improved measurements of the differential production rates of stable charged particles in hadronic Z0 decays, and of charged pions, kaons, and protons identified over a wide momentum range using the SLD Cherenkov ring imaging detector. In addition to flavor-inclusive Z0 decays, measurements are made for Z0 decays into light (u, d, s), c, and b primary flavors, selected using the upgraded vertex detector. Large differences between the flavors are observed that are qualitatively consistent with expectations based upon previously measured production and decay properties of heavy hadrons. These results are used to test the predictions of QCD in the modified leading logarithm approximation, with the ansatz of local parton-hadron duality, and the predictions of three models of the hadronization process. The light-flavor results provide improved tests of these predictions; the heavy-flavor results provide complementary model tests. In addition we have compared hadron and antihadron production in light quark (as opposed to antiquark) jets. Differences are observed at high momentum for all three charged hadron species, providing direct probes of leading particle effects, and stringent constraints on models. © 2004 The American Physical Society.

Abstract

We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, m(Z) and Gamma(Z), and its couplings to fermions, for example the p parameter and the effective electroweak mixing angle for leptons, are precisely measured: m(Z) = 91.1875 +/- 0.0021 GeV, Gamma(Z) = 2.4952 +/- 0.0023 GeV, rho(l) = 1.0050 +/- 0.0010, sin(2)theta(eff)(lept) = 0.23153 +/- 0.00016. The number of light neutrino species is determined to be 2.9840 +/- 0.0082, in agreement with the three observed generations of fundamental fermions. The results are compared to the predictions of the Standard Model (SM). At the Z-pole, electroweak radiative corrections beyond the running of the QED and QCD coupling constants are observed with a significance of five standard deviations, and in agreement with the Standard Model. Of the many Z-pole measurements, the forward-backward asymmetry in b-quark production shows the largest difference with respect to its SM expectation, at the level of 2.8 standard deviations. Through radiative corrections evaluated in the framework of the Standard Model, the Z-pole data are also used to predict the mass of the top quark, m(t) = 173(+10)(+13) GeV, and the mass of the W boson, m(W) = 80.363 +/- 0.032 GeV. These indirect constraints are compared to the direct measurements, providing a stringent test of the SM. Using in addition the direct measurements of m(t) and m(W), the mass of the as yet unobserved SM Higgs boson is predicted with a relative uncertainty of about 50% and found to be less than 285 GeV at 95% confidence level.

Abstract

Exploiting the manipulation of the SLAC Linear Collider electron-beam polarization, we present precise direct measurements of the parity-violation parameters Ac and Ab in the Z-boson-c-quark and Z-boson-b-quark coupling. Quark-antiquark discrimination is accomplished via a unique algorithm that takes advantage of the precise SLAC Large Detector charge coupled device vertex detector, employing the net charge of displaced vertices as well as the charge of kaons that emanate from those vertices. From the 1996-1998 sample of 400000 Z decays, produced with an average beam polarization of 73.4%, we find Ac = 0.673 ± 0.029(stat) ± 0.023(syst) and Ab = 0.919 ± 0.018(stat) ± 0.017(syst). © 2005 The American Physical Society.

Abstract

We study the decays B- → D*0π - and B-→ D*0K-, where the D*0 decays into D0π0, with the D0 reconstructed in the CP-even (CP+) eigenstates K-K + and π-π+ and in the (non-CP) channels K-π+, K -π+π+π-, and K -π+π0. Using a sample of about 123 × 106 BB̄ pairs, we measure the ratios of decay rates R*non-CP ≡ B(B- → D* non-CP 0K-)/B(B- → D*non-CP 0π-) = 0.086 ± 0.0040(stat)-0.0031 +0.0042(syst), and provide the first measurements of R*CP+ ≡ B(B- → D*CP+ 0K-)/B(B- → D*CP+ 0π-) = 0.0086 ± 0.021(stat) ± 0.007(syst), and of the CP asymmetry A*CP+ ≡ B(B- → D*CP+ 0K -)-B(B+ → D*CP+ 0K +)/B(B- → D*CP+ 0K -)+B(B+ → D*CP+ 0K +) = 0.10 ± 0.23(stat)-0.04 +0.03(syst). © 2005 The American Physical Society.

Abstract

We present improved measurements of the differential production rates of stable charged particles in hadronic Z0 decays, and of charged pions, kaons, and protons identified over a wide momentum range using the SLD Cherenkov ring imaging detector. In addition to flavor-inclusive Z0 decays, measurements are made for Z0 decays into light (u, d, s), c, and b primary flavors, selected using the upgraded vertex detector. Large differences between the flavors are observed that are qualitatively consistent with expectations based upon previously measured production and decay properties of heavy hadrons. These results are used to test the predictions of QCD in the modified leading logarithm approximation, with the ansatz of local parton-hadron duality, and the predictions of three models of the hadronization process. The light-flavor results provide improved tests of these predictions; the heavy-flavor results provide complementary model tests. In addition we have compared hadron and antihadron production in light quark (as opposed to antiquark) jets. Differences are observed at high momentum for all three charged hadron species, providing direct probes of leading particle effects, and stringent constraints on models. © 2004 The American Physical Society.

Abstract

We report a search for Bs0-Bs0 oscillations using a sample of 400 000 hadronic Z0 decays collected by the SLD experiment. The analysis takes advantage of the electron beam polarization as well as information from the hemisphere opposite that of the reconstructed B decay to tag the B production flavor. The excellent resolution provided by the pixel CCD vertex detector is exploited to cleanly reconstruct both B and cascade D decay vertices, and tag the B decay flavor from the charge difference between them. We exclude the following values of the B s0-B̄s0 oscillation frequency: Δms

Abstract

A search for B0s-B0s oscillations is performed using a sample of 400 000 hadronic Z0 decays collected by the SLAC Large Detector experiment. The B0s candidates are reconstructed in the B0s→D-sX channel with D-s→Ππ-, K*0K-. The B0s production flavor is determined using the large forward-backward asymmetry of polarized Z0→bb decays and charge information in the hemisphere opposite that of the B0s candidate. The decay flavor is tagged by the charge of the D±s. From a sample of 361 candidates with an average B0s purity of 40%, we exclude the following values of the oscillation frequency: Δms

Abstract

A search for B 0s-B̄ 0s oscillations is performed using a sample of 400 000 hadronic Z 0 decays collected by the SLAG Large Detector experiment. The B 0s candidates are reconstructed in the B 0s→D -sX channel with D -s→Φπ -, K* 0K -. The B 0s production flavor is determined using the large forward-backward asymmetry of polarized Z 0→bb̄ decays and charge information in the hemisphere opposite that of the B 0s candidate. The decay flavor is tagged by the charge of the D ±s. From a sample of 361 candidates with an average B 0s purity of 40%, we exclude the following values of the oscillation frequency: Δm s

Abstract

The structure of 3-jet e+ e- → bb̄g events has been studied using hadronic Z0 decays recorded in the SLC Large Detector experiment at SLAC. Three-jet final states were selected and the charge-coupled-device-based vertex detector was used to identify two of the jets as b or b̄; the remaining jet in each event was tagged as the gluon jet. Distributions of the gluon energy and polar angle with respect to the electron beam were measured over the full kinematic range, and used to test the predictions of perturbative QCD. We find that beyond-leading-order QCD calculations are needed to reproduce the features seen in the data. The energy distribution is sensitive to an anomalous b chromomagnetic moment K at the bb̄g vertex. We measured κ to be consistent with zero and set 95% confidence level limits on its value, -0.06

Abstract

We have made the first direct symmetry tests in the decays of polarized Z0 bosons into fully identified bbg states, collected in the SLD experiment at SLAC. We searched for evidence of parity violation at the bbg vertex by studying the asymmetries in the b-quark polar- and azimuthal-angle distributions, and for evidence of T-odd, CP-even or CP-odd, final-state interactions by measuring angular correlations between the three-jet plane and the Z0 polarization. We found results consistent with standard model expectations and set 95% C. limits on anomalous contributions.

Abstract

We have developed a new technique for inclusive reconstruction of the energy of B hadrons. The excellent efficiency and resolution of this technique allow us to make the most precise determination of the b-quark fragmentation function, using e+e-→Z0 decays recorded in the SLAC Large Detector experiment. We compared our measurement with the predictions of a number of fragmentation models. We excluded several of these models and measured the average scaled energy of weakly decaying B hadrons to be (xB) = 0.714 ± 0.005(stat) ± 0.007(syst) ± 0.002 (model dependence). © 2000 The American Physical Society.

Abstract

The parity violation parameters Ab and Ac of the Zbb¯ and Zcc¯ couplings have been measured directly, using the polar angle dependence of the Z0-pole polarized cross sections. Bottom and charmed hadrons were tagged via semileptonic decays. Both the muon and electron identification algorithms take advantage of new multivariate techniques, incorporating for the first time information from the SLD Čerenkov Ring Imaging Detector. Based on the 1993–1995 SLD sample of 150 000 Z0 decays produced with highly polarized electron beams, we measure Ab=0.910±0.068(stat)±0.037(syst), Ac=0.642±0.110(stat)±0.063(syst).

Abstract

We present evidence for leading particle production in hadronic decays of the Z0 boson to light-flavor jets. A polarized electron beam was used to tag quark and antiquark jets, and a vertex detector was employed to reject heavy-flavor events. Charged hadrons were identified with a Cherenkov ring imaging detector. In the quark jets, more high-momentum p, Λ, K-, and anti K¯*0 were observed than their antiparticles, and vice versa for antiquark jets, providing direct evidence that the higher-momentum particles in jets are more likely to carry the primary quark or antiquark from the Z0 decay, and that ss¯ production is suppressed in fragmentation.

Abstract

We present the first measurement of the left-right charge asymmetry [Formula presented] in hadronic Z boson decays. This was performed at [Formula presented] with the SLD at the SLAC Linear Collider with a polarized electron beam. Using 89838 events, we obtain [Formula presented] which leads to a measurement of the electron left-right asymmetry parameter, [Formula presented], and [Formula presented]. Also, the [Formula presented] measurement combined with the left-right cross section asymmetry determines A_e independently of the value of the electron-beam polarization.

Abstract

The strong coupling αs(MZ2) has been measured using hadronic decays of Z0 bosons collected by the SLD experiment at SLAC. The data were compared with QCD predictions both at fixed order O(αs2) and including resummed analytic formulas based on the next-to-leading logarithm approximation. In this comprehensive analysis we studied event shapes, jet rates, particle correlations, and angular energy flow, and checked the consistency between αs(MZ2) values extracted from these different measures. Combining all results we obtain αs(MZ2)= 0.1200±0.0025 (expt) ±0.0078 (theor), where the dominant uncertainty is from uncalculated higher order contributions.

Abstract

We have searched for signatures of polarization in hadronic jets from Z0→qq̄ decays using the "jet handedness" method. The polar angle asymmetry induced by the high SLAC Linear Collider electron-beam polarization was used to separate quark jets from antiquark jets, expected to be left and right polarized, respectively. We find no evidence for jet handedness in our global sample or in a sample of light quark jets, and we set upper limits at the 95% C.L. of 0.063 and 0.099, respectively, on the magnitude of the analyzing power of the method proposed by Efremov et al.

Abstract

We present a direct measurement of Ac=2vcac(vc2+ac2) from the left-right forward-backward asymmetry of D*+ and D+ mesons in Z0 events produced with the longitudinally polarized SLAC Linear Collider beam. These Z0→cc̄ events are tagged on the basis of event kinematics and decay topology from a sample of hadronic Z0 decays recorded by the SLAC Large Detector. We measure Ac0=0.73±0.22(stat)±0.10(syst).

Abstract

Using an impact parameter tag to select an enriched sample of Z0→bb̄ events, and the net momentum-weighted track charge to identify the sign of the charge of the underlying b quark, we have measured the left-right forward-backward asymmetry for b quark production as a function of polar angle. Based on 1.8 pb-1 of Z0 decay data produced with a mean electron beam polarization of Pe=63%, this yields a direct measurement of the extent of parity violation in the Zbb coupling of Ab=0.87±0.11(stat)±0. 09(syst).

Abstract

The parity-violating parameters Ab and Ac are directly measured by the SLD experiment at the SLAC Linear Collider in e+e- collisions with polarized electrons at the Z0 resonance. Leptons with distinctive total and transverse momenta are used to select and analyze Z0→bb̄ and Z0→cc̄ events. Ab and Ac are extracted by forming the left-right forward-backward asymmetry in electron beam polarization and quark polar angle. From our 1993 sample of 1.8 pb-1 of Z0 decay data with an average electron beam polarization of 63% we find Ab=0.91±0.14 (stat) ± 0.07 (syst) and Ac=0.37±0.23 (stat) ± 0.21 (syst).

Abstract

Using an impact parameter tag to select an enriched sample of Z0→bb̄ events, we have measured the difference between the average charged multiplicity of Z0→bb̄ and Z0→ hadrons to be n̄b-n̄had=2.24±0.30 (stat) ±0.33 (syst) tracks per event. From this, we have derived n̄b-n̄uds=3.31±0.41±0. 79. Comparing this measurement with those at lower center-of-mass energies, we find no evidence that n̄b-n̄uds depends on energy. This result is in agreement with a precise prediction of perturbative QCD, and supports the notion that QCD remains asymptotically free down to the scale Mb2.

Abstract

We determine the strong coupling αs from a comprehensive study of energy-energy correlations (EEC) and their asymmetry (AEEC) in hadronic decays of Z0 bosons collected by the SLD experiment at SLAC. The data are compared with all four available predictions of QCD calculated up to O(α2 s) in perturbation theory, and also with a resummed calculation matched to all four of these calculations. We find large discrepancies between a, values extracted from the different O(α2 s) calculations. We also find a large renormalization scale ambiguity in αs determined from the EEC using the 0(α2 s) calculations; this ambiguity is reduced in the case of the AEEC and is very small when the matched calculations are used. Averaging over all calculations, and over the EEC and AEEC results, we obtain αs(M2 z) = 0.124+0.003 -0.004(expt.)±0.009(theory).

Abstract

We have determined the strong coupling αs from measurements of jet rates in hadronic decays of Z0 bosons collected by the SLD experiment at SLAC. Using six collinear and infrared safe jet algorithms we compared our data with the predictions of QCD calculated up to second order in perturbation theory, and also with resummed calculations. We find αs(MZ2)=0.118±0.002(stat)±0.003(syst)±0.010(theory), where the dominant uncertainty is from uncalculated higher order contributions.

Abstract

We present the first measurement of the left-right cross section asymmetry (ALR) for Z boson production by e+e- collisions. The measurement was performed at a center-of-mass energy of 91.55 GeV with the SLD detector at the SLAC Linear Collider which utilized a longitudinally polarized electron beam. The average beam polarization was (22.4±0.6)%. Using a sample of 10 224 Z decays, we measure ALR to be 0.100±0.044(stat)±0.004(syst), which determines the effective weak mixing angle to be sin2θWeff=0.2378 ±0.0056(stat)±0.0005(syst).

Abstract

The parity violation parameters Ab and Ac of the Zbb ̄ and Zcc ̄ couplings have been measured directly, using the polar angle dependence of the Z0-pole polarized cross sections. Bottom and charmed hadrons were tagged via semileptonic decays. Both the muon and electron identification algorithms take advantage of new multivariate techniques, incorporating for the first time information from the SLD Čerenkov Ring Imaging Detector. Based on the 1993–1995 SLD sample of 150 000 Z0 decays produced with highly polarized electron beams, we measure Ab=0.910±0.068(stat)±0.037(syst), Ac=0.642±0.110(stat)±0.063(syst).
